What does a red flag signal at a sailing venue?

A red flag at a sailing venue is a clear signal indicating dangerous weather conditions. This warning is crucial for the safety of sailors, as it alerts them to hazardous situations such as approaching storms, high winds, rough seas, or other risks that could make sailing dangerous.

The use of color-coded flags in sailing is a standard practice, with red specifically designated to prompt caution. Sailors must take this signal seriously and avoid heading out onto the water, as conditions may deteriorate rapidly.

In contrast, calm weather would not necessitate a red flag; instead, it would typically be signaled with a different color or no flag at all. Similarly, fair weather conditions would not warrant a red flag, nor would restricted areas be indicated by a red flag, as those would have their own specific warnings or indicators.
